Patent GB-1008980-A (GB)
Title: Improvements in or relating to breathing apparatus
Inventor: FITT PETER WILLIAM
IPC: A62B9/02
Filed: 1963-01-15
Abstract: 1,008,980. Breathing apparatus. NORMALAIR Ltd. Jan. 8, 1964 [Jan. 15, 1963], No. 1878/63. Heading A5T. A breathing apparatus for use in aircraft comprises a first and second demand type breathable gas regulator 1 and 17, the first and second regulators respectively providing a controlled gas delivery for inhalation to mask or helmet 2 and for inflation of pressure apparel 19, and the regulator 17 when exposed to ambient pressure below a predetermined datum providing overriding control of regulator 1. The regulators 1 and 17 are disconnectably interconnected to a common gas source via conduits 10 and 30 and are also connected by conduit 28. The regulator 1 comprises demand chamber 3 in communication with helmet 2, datum chamber 4 for controlling the supply of gas to demand chamber 3 and aneroid 8 for controlling the pressure in datum chamber 4. Similarly the regulator 17 comprises demand chamber 24 in communication with apparel 19, datum chamber 21 and aneroid 22. Aneroid 8 in control chamber 7 is under the overriding control of aneroid 22 which is subject to ambient pressure. The chamber 7 has a vent 9 which is under the control of a relay device comprising diaphragm 25 and conduit 26 connected to line 28 leading to demand chamber 24. Alternatively the diaphragm 25 may be omitted and the conduit 26 leads through the vent 9 and line 28 leads to datum chamber 21. The apparatus is provided with compensating expuratory and discharge valves 13 and 18. In use at altitudes above a predetermined pressure gas is supplied to mark 2 via valve 11 and "control bleed air" passes via orifices 10a and 34 and is vented to the atmosphere via datum chambers 4 and 21. At higher altitudes the pressure is such that the aneroid 22 closes datum chamber 21 so that the pressure increases in chamber 21. This pressure in datum chamber 21 is exerted on the sensing chamber of the discharge valve 18 and sensing diaphragm 37 controlling gas delivery from regulator 17 such as to balance delivery to and discharge from the garments 19 to maintain the required pressure therein. The pressure increase in datum chamber 21 causes throttling of the vent 9 such that the pressure in datum chamber 4 increases and influences the sensing diaphragm 6 to deliver gas to mask 2 at a pressure matching the pressure conditions in garments 19.

Title: Improvements in methods of gramophone reproduction
IPC: G11B7/00
Filed: 1929-01-21
Abstract: 328,317. Williams, W. E. Jan. 21, 1929. Optical apparatus.-Sound is reproduced from a grooved sound record by means of a beam of light projected upon the record and passed, after reflection therefrom, through an optical system and a suitably shaped or tinted diaphragm to a light-sensitive device connected to a thermionic amplifier with a loud-speaker. This process may be used for monitoring purposes. The record may be an initial wax record, or a positive or negativeelectroplate of the wax master, or an ordinary commercial lateral-cut or hill-and-dale record.. With hill-and-dale records the variations of the reflected light are produced by the varying distance of the bottom of the groove from the fixed focus of the optical system. To ensurebetter reflection, the record may be metallized by chemical deposition, or cathodic spluttering, or other method, the metallic film being deposited in the groove or on the other parts or both. The diaphragms may have slots of single or double triangular shape with straight or concave sides, or may be tinted wedges which may be combined with clear wedges to compensate for deviation. The optical eystem for the reflected beam may also be used for the projection of the beam on the record. As shown in Fig. 8, light from a source 18 passes through a condenser 19 and a diaphragm 20 to a prism 21 and is there reflected to another reflecting prism 27 from which it passes through a lens system 22 to the record R.. The reflected light passes back through the lens system 22 and reflecting prism 27, and thencethrough a diaphragm 24 to a light-sensitive device 10. Means may be provided to vary the light intensity to control the volume of sound. The optical system may be carried by a member 28 mounted like a tone-arm, for example on a fulcrum 32, or on a parallel-link motion 31, and mav be held up at the correct distance from the record in various ways, for example by a spring- cushioned stylus or roller 30 riding in a groove,. or by a bridge mounted on rollers running on smooth parts of the record. Cams and levers may be used to ensure correct tracking; and rollers may be provided and the turntable driven by a flexible shaft to correct for eccentricity and. vertical irregularities.

Abstract: 347,256. Kinematograph apparatus. EMERSON, L., 30, Cavendish Road, Sutton, Surrey. Jan. 22, 1930, No. 2183. [Class 97 (i).] In a portable kinematographic appliance for teaching dancing of the type comprising a frame carrying hand-operated intermittent feed mechanism and in which the film is directly observed in the gate by means of a lens, the lens-holder is movable away from the gate to enable the film to be introduced into operative position through openings in the frame without disassembling the feed mechanism. As shown in Fig. 2, the pictures are viewed through the lens 1 mounted in a holder 2 attached to a bracket 5a pivoted to the frame 6. The gate-plate 8 hinged at 9 can be swung away from the guide-plate 10, Fig. 3. The channel 12 for the film and the co-operating gate channel 13 are extended to form arcuate guides 16, 18, the upper end of 18 carrying a spring 19 pressing on the sprocket 20.

Abstract: 469,405. Fluid - friction brakes. AKTIEBOLAGET LJUNGSTROMS ANGTURBIN. Jan. 23, 1936, No. 2218. Convention date, Feb. 1, 1935. [Class 103 (i)] [Also in Group XXVII] Braking means for an internal combustion engine comprises a screw compressor driven by the engine, the outlet of which is adapted to be freely opened, to be throttled while the compressor is shut off from the en gine or to be connected to the air intake of the engine, thereby running idle, acting as a brake or serving as a pre-compressor for the engine. A valve 7 is arranged between the compres sor 5 and the carburetter 13 operated by a lever 8 and in the position shown connects the compressor to the carburetter. The valve 7 may be turned to connect the compressor freely to the exhaust pipe 12 by a pipe 16 or may be moved to an intermediate position to throttle the compressor. The compressed air flow is distributed between the engine and a pipe 17 leading to the exhaust pipe 12 by the throttle valve 19 and a valve 18, these valves being connected together by a link 20 so that one is opened when the other is closed. The passage 23 in the valve 7 is of such a shape that the compressor outlet can never be completely closed. For oil motors a groove in the valve 7 may connect the compressor and the motor when the valve is closed. Specifications 464,475, 464,493, and 464,494, [all in Group XXVI], are referred to.

Abstract: 267,477. Autier, J., Autier, M., and Autier, V. March 9, 1926, [Convention date]. Valves controlled by pilot or relay valves.-An oscillating disc valve 44 is actuated by, a doubleacting piston acting through a lever 50 and quickpitched screw 48. The supply and exhaust of actuating fluid to and from the two ends of the cylinder are controlled by a hand-actuated fourway plug-cock. The Specification as open to inspection under Sect. 91 (3) (a) comprises also a modification shown in Fig. 1 (Cancelled), in which the main valve 11 is opened against conduit pressure by admitting inlet pressure below the main actuating piston 16. Pressure is supplied to the actuating chamber through a port 21 and passage 19 and is exhausted through passage 19, port 22, and passage 23, both inlet and exhaust being controlled by a double-seated auxiliary valve 24 actuated by a screwed spindle 25. Modifications are described in which the control of the auxiliary valve is modified to enable the device to function as a pressure-regulating or safety valve. This subject-matter does not appear in the Specification as accepted.
